IMPROVEMENT IN .SASH-HOLDERS.

Owv- The Schedule referred 'to in these Letters Patent and making part of the same.

I, R. B. HUGUNIN, of Cleveland, Ohio, have invented certain Improvements in Sash-Holders, gf which the following is a specification.

Nature of Invention.

My invention relates to the use of a roller or rollers, suspended'in a plate, with a grooved end, the grooves running the direction the lroller turns, the object being to furnish sufcient resistance to prevent the roller from turning by the weight of the sash, and, at the same time, allow it to turn when the sash is being pressed down by hand. The amount of holding-power is regulated by the number and width of the grooves,

or extent of friction-surface. The projections furnish the friction, and the indentedsurface, while afl fording no resistance, allows the coming of the roller to relieve itself fromV any tendency to bank up or clamp.

And also to the use, in combination with the above, of V-shaped springs, construct-ed` with slots on their upper sides, and holes in ltheir lower sides, and used for eiiciently forcing the sash-holder outward, with suicient power to prevent the rollers from sliding on the casing vfrom the weight of the sash.

Description of Drawings Accompanying this Specificat/ion.

General Description. f

A, upper part of roller-plate. B, lower part of roller-plate. This plate is cast in halves, because more yeasily made.

C and C', projections extending up from lower half of plate 4A B,for the purpose of holding the roller up against the groovcd surface, and p reventing its moving downward during the upward movement of the sash.

The roller fits between these projections and the grooves, so as to avoid any dropping back of the sash after it is let go of by the hand, while the roller is coming in contact with the grooves, to support it, &c.

The angle of the grooves, in reference to the surface of the roller, is such, being almost a tangent,

that it can roll freely when the sash is raised, though in close contact when the motionis reversed, owing lto the different angles of pressure.

Close contact, all the time, is Ythe proper position of my roller withlreference to the grooves, but, after a whilefwear willV occur, and thediameter be diminished ;-thus a space will disadvantageously occur, Ste.V

A substitute for this projection is illustrated in fig. 4. When the projections are not used, a grooved surface, D', anti-friction from the angle of pressure during the upward motion of the sash, is substituted on the upper inside end of plate A, being on the opposite endA from the grooved friction-surface in plate B. This grooved surface will confine the roller in position on the surface D, during the upward motion of the sash, ydto.

D, grooved surface in plate A B. These grooves vrun in the direction the rollers turn, and may be of any suitable width, depth, or angle, &c. They afford ample holding-friction, and, at the same time, allow the roller to turn when the sash is being pressed down by hand without clamping it, so as 'to tear off thecovering, 85o. The projections furnish the friction,

andthe indented surface,'while offering no friction, allowsthe covering to relieve'itself from any tendency'y to ban/k up and clamp. With the grooves, the desired frictionl can be regulated and obtained for sash-holder purposes.

E, a yielding or semi-elastic covered roller. The

covering should consist of a rigid, durable substance.`

Alternate layers of rubber and cloth, or rubber and felt, vulcanized comparatively hard, are, perhaps, as good as any. Glotl1,cale11dered, with sufiic'ient rubber Vto cover it, and then rolled up in the form of tubing,

and vulcanized, then cut to the right lengths to slip over the body of the roller, and cemented there, I use'and prefer.

F and F', steel springs, with slots out in their upper sides, and holes punched in their lower, the hole to hold the spring in position, and the slot to allow it to spring independently of any fastenings, dsc.

One of these springs is putin eachend of the inortise in the sash for the psash-holder, and secured down through there by means of the screws passing the holes in the lower halves, &c.

When the sash is new, little space occurs between it and the'casi'ng; but in time, by shrinkage, half an inch frequently occurs. It is necessary to overcome this to make a sash-holder of any lasting value. I accomplish this result by means of these springs. -I screw the holder down in the mortise, so that its outer face will be on a line with the edge of the sash, then compress the rollers back into the mortise, so as to allow the sash to enter the casing. When shrinkage occurs, if the springs are good, the holder is forced outward, and iills the space, Sac.

G and G', common Wood-screws for securing the holder to the sash, 85o.

Claims.

I claim- 4 1. The longtudnally-grooved surface D, substantially as and for the purposes herein described.

2. The longtudinally-grooved surface D, roller E,

projection O, in plate A B, substantially as and for the purposes herein described. 3. 1n combina-tion with the elements of the second claim, the slotted springs F and F', for the purposes herein specified.
